Corrosion Behavior of Nickel–Titanium Continuous-Casted Alloys
(MDPI, 2024)
Variations in the corrosion behavior of biomedical NiTi alloys in Cl− containing and acidic environments present a problem with their biological implantation. The objective of this research was to evaluate the synergy of ...
Exposure Factors in Health Risk Assessment of Heavy Metal(loid)s in Soil and Sediment
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Heavy metal(loid)s (HMs) play an important role in economic development since they are used in various branches of industry. However, all industrial activities emit HMs into the environment, where they are no longer useful ...
Application of the Composite Hardness Models in the Analysis of Mechanical Characteristics of Electrolytically Deposited Copper Coatings: The Effect of the Type of Substrate
(Metals, 2021)
The mechanical characteristics of electrochemically deposited copper coatings have been examined by application of two hardness composite models: the Chicot-Lesage (C-L) and the Cheng-Gao (C-G) models. The 10, 20, 40 and ...
Black Pine (Pinus nigra) Essential Oil as a Green Corrosion Inhibitor for Carbon Steel
(MDPI, 2023)
In this work, the essential oil of black pine (Pinus nigra J. F. Arnold) was used for the first time as a natural, ecological, and sustainable corrosion inhibitor for the acid cleaning of carbon steel. The essential oil ...
